Abstract

This paper analyzes the mobile data traffic traces of a CDMA network and presents its unique characteristics compared to the wired Internet traffic. The data set was passively collected from the backbone of a commercial mobile service provider. Our study shows the highly uneven up/downlink traffic utilization nature in mobile data networks along with small packet sizes, so called the mice in the network. In addition, the relatively short session length reflects the user behavior in mobile data network. We have also observed a large amount of retransmissions on the backbone and analyzed the consequences of such phenomenon as well as the possible causes.
